Oh don't start me on M&S!
A couple of years back I ordered a mattress, then cancelled it about an hour later.
(In hindsight I think I did this twice, as I was being indecisive)
The mattress turned up and was dumped outside my door when I was out - not even under the porch, just leaning all haphazard against a wall.
I had to give this thing house room for about a week until they could arrange to come and get it. Seriously a double mattress, it's no joke.
They then brought it again, a total of FOUR TIMES a few days apart each time, I was lucky to be in each time and refused delivery - but it wasn't that they had the two orders (and not been told it was cancelled) because it was the SAME sodding mattress each time, same increasingly withered wrapping etc etc.
I had to make about 20 phone calls to various CS call centres, warehouses and delivery depots before someone actually cancelled it from coming back yet again...
then this summer I thought 'they can't mess up a clothes order' and ordered a load of school trousers and tights for me. They didn't turn up...2 or 3 weeks later I rang them and they quoted my old address back at me...I am certain I entered the new one when I ordered, it just defaulted to the old one and there was nothing they could do as the parcel had been sent to my old house...well, presumably, as they had NO TRACKING and had no idea where it was and it MIGHT get returned to them or on the other hand it might not, if the people who lived there accepted it or postman had just left it outside
Thank goodness the sorting office had it. I was fuming, I'm never ordering from them again especially reading this thread. The whole system's just so lax, and ineffectual.
